RESUMO
Objective: To study on the molecular mechanism of anti-platelet aggregation and anti-thrombosis of Sparganii Rhizoma. Method: Based on the data information and analysis functions of traditional Chinese medicine(TCM) database,TCM composition database and target database in TCM platform for integration of pharmacology,information of chemical compositions in Sparganii Rhizoma was retrieved,interaction network between potential targets of Sparganii Rhizoma and disease targets was built,and the key targets were enriched and calculated,the gene functions and pathways were analyzed,multidimensional relationship network of " herbal medicines-chemical components-key targets-key pathways" was built. Result: Active ingredients of Sparganii Rhizoma mainly included flavonoids and phenolic acids,such as mountain kaempferol,sanleng acid,linoleic acid,etc.Anti-thrombosis involved 202 key targets,including protein kinase Cδ(PRKCD),glucose kinase(GCK),(PRKAA2),adenosine ribonucleotide activated protein kinase α-2 catalytic subunit,etc;and it was related to the endocrine system,circulatory system,neurodegenerative diseases and other related biological processes and signal pathways.Anti-platelet aggregation involved 136 key targets,including PRKCD,cytochrome C oxidase protein 7C(COX7C),GCK,etc;and it was involved in Parkinson's disease,circulatory system,neurodegenerative diseases and other related biological processes and signal pathways. Conclusion: Sparganii Rhizoma regulates vascular endothelial cell adhesion molecule expression and platelet mitochondrial function mediated apoptosis of platelets mainly through regulating neurotransmitter activity in the central nervous system,in order to exert antithrombotic effect and anti-platelet aggregation effect.
RESUMO
Objective: To explore the interrelation of "composition-target-disease" of Kaixinsan on treatment of Alzheimer's disease. Method: Through the integrated pharmacological platform of Chinese medicine V1.0,the active ingredients and potential targets of four Chinese herbs in Kaixinsan were collected,disease targets of Alzheimer's disease were searched,and enriched by the gene ontology database and the Kyoto encyclopedia of genes and genomes at hubs. Result: Among the 250 compounds of Kaixinsan,2 877 targets were associated with Alzheimer's disease.The key targets,such as mitochondrial trifunctional enzyme subunit alpha(HADHA),hydroxyacyl coenzyme A dehydrogenase(HADH),sterol-4-alpha-carboxylate 3-dehydrogenase(NSDHL) and others,played their pharmacological effects mainly through regulating purine and nucleotide metabolism,Huntington's disease,Alzheimer's disease,neurodegenerative diseases,oxidative phosphorylation,and endocrine and metabolic diseases in molecular reactions,such as cytoplasm,mitochondria,adenosine triphosphate binding,and mitochondrial matrix. Conclusion: The platform can predict the key targets and related pathways of Kaixinsan for treatment of Alzheimer's disease,which lays the foundation for further revealing material basis and mechanism of this formula,and plays an important role in digging and developing this classic and famous formula.
